Diagnosis of clear-cut severing of the two flexor tendons is simple and obvious. This is not true for isolated injury to a single tendon and for partial severing. In this case, careful clinical examination and routine surgical exploration of any wound with regard to the course of the flexor tendon is required. Surgery should aim at the least traumatic repair possible, followed by specialised rehabilitation directed by the surgeon. In the distal region, reinsertion into the bone is required. In other regions, suture consists of a the main suture with a continuous suture of the epitendineum. The region of the digital canal requires rigourous care due to its specific anatomy. The corollary to good surgical repair is rehabilitation, understood and complied with by the patient. Early mobilisation procedures are used predominantly in order to avoid the formation of postsurgical adherences.
